This car starts decent cold, but when warm you have to crank it a while but it always starts, I have a pressure gauge hooked up at the tank when running the pressure is 40 lbs turn it off and it immediately drops to 33 lbs then in about 3 minutes will slowly drop to 20 lbs then losses a 1 lbs a minute til there is no pressure reading. At 20 lbs it will still start right up but below that you have to crank it awhile. I have replaced the fuel filter, an ebay tank and pump unit, cleaned the mass air flow sensor and the throttle body including the opening to the throttle positioner and removed and cleaned the throttle positioner, Cleaned all the connectors and ran 2 tanks with high quality fuel injector cleaner. Any suggestions or things to test before I throw more parts at it that unfornately change nothing?
